Reply To: What is the appropriate punishment for financial crimes?

gavra – halacha has provisions specifying what the penalties are for wronging an aino yehudi. As a rule of thumb, the penalties are more severe when the wronged party is a member of klal yisroel.

But first you have to decide jurisdiction. I have not seen a source (including Rav Moshe) that says Bais Din has jurisdiction when the argument is between a Jew and non-Jew. My understanding is that secular court would have jurisdiction.

As far as Mored B’malchus, I’m willing to allow you time for research. 🙂 Let us know what you find.
